Leviticus 14:43-54

⁴³And if the disease comes out again in the house after he has taken out the stones and after the walls have been rubbed and the new paste put on,

⁴⁴Then the priest will come and see it; and if the disease in the house is increased in size, it is the leper's disease working out in the house: it is unclean.

⁴⁵And the house will have to be pulled down, the stones of it and the wood and the paste; and everything is to be taken out to an unclean place outside the town.

⁴⁶And, in addition, anyone who goes into the house at any time, while it is shut up, will be unclean till evening.

⁴⁷And anyone who has been sleeping in the house will have to have his clothing washed; and anyone who takes food in that house will have to have his clothing washed.

⁴⁸And if the priest comes in, and sees that the disease is not increased after the new paste has been put on the house, then the priest will say that the house is clean, because the disease is gone.

⁴⁹And in order to make the house clean, let him take two birds and cedar-wood and red thread and hyssop;

⁵⁰And put one of the birds to death in a vessel of earth over flowing water;

⁵¹And take the cedar-wood and the hyssop and the red thread and the living bird and put them in the blood of the dead bird and in the flowing water, shaking it over the house seven times.

⁵²And he will make the house clean with the blood of the bird and the flowing water and with the living bird and with the cedar-wood and the hyssop and the red thread.

⁵³But he will let the living bird go out of the town into the open country; so he will take away sin from the house and it will be clean.

⁵⁴This is the law for all signs of the leper's disease and for skin diseases;
